To all whom it may concern:

Be it known that l, HOWARD SMALL, of l vyncote, in the county ofMontgomery and State of Pennsylvania, have invented certain new anduseful Improvements in Vacuum Cleaning Apparatus, whereof the tollowingis a specification, reference'being had to the accompanying drawings.

My invention relates to a vacuum cleaner of the light portable type inwhich the motor, fan and dust bag are supported axially between thehandle and the cleaning tool.

My invention relates more specifically to a construction whereby this isaccomplished in such a way as to permit these intermediate parts to bemounted nearer the cleaning tool than to the handle without so enema--bering the parts as to impede the use of the tool.

It is important that the tool be free to pass under furniture, and thelarger parts of the cleaner must not interfere with this use. lit isalso important that for the purpose of proper manipulation the handleand the related part of the shaft should be free in order to properlymanipulate the tool.

The whole tool must be made as light as possible and the constructionwhich T have invented consists in a combination of parts whichaccomplishes all these ends,

in the accompanying drawings, ll have illustrated a vacuum cleaner whichembodies my invention.

Figure T, is a side elevation of such a cleaner. Fig. H, is an enlargedcentral sectional view of the motor fan and dust receptacle. The lowerportion of this figure is a staggered section as indicated by the arrowsHTT, in Fig. Tlll. lFig. llllll, is a cross section along the linelllll, Tllll, of Fig. H.

The handle 1, is formed upon the upper end of a hollow shaft throughwhich is passed the cable 2, comprising the wires by which the motor isoperated. To the lower end of this shaft there is attached a motorcasing 3, which may conveniently be formed ofbell shape, as shown, witha bearing 5, inserted at the top and also a bearing 6, sustained at thebottom of the bell by the annular disk 7, which is attached to the lowerflange of the bell shaped casing.

Within these hearings is mounted the motor shaft 8, carrying thecommutator 9, and the armature 10, of an electric motor, of which thefieldcoils are indicated at 11, being set within the motor casing. Thismotor may be appropriately ventilated by the fan 12, and draft apertures13, and 14. The motor shaft 8, projects through its lower bearing andthere carries, with the interposition of a nut 15, a fan 16. To theflange of the motor casing is attached an annular disk 18, with a flange19. The suction tube 20, which is in alinement with the shaft of thetool, and also with the motor shaft, carries the cleaning tool 21, atthe lower end, while its upper end carries a disk 23, which is united tothe above mentioned flange 19. The disk 23, is pierced by apertures 30,through which the dust laden air which has passed directly from thesuction tube into the fan chamber is discharged from the lower side ofthe fan passing between a row of arms 26, which run from the flange 19,to a ring 22, surrounding the suction tube and forming the lower side ofthe fan casing. e

A dust bag 40, of a fabric suitable for dust filtering, is attached atits upper end to a ring 41, which surrounds the flange 19. The lower endof this dust bag, which takes the form of an elongated cylinder, isattached to a collar 42, which slides telescopically upon the vacuumtube projecting well up within the dust bag so that when it is desiredto empty the dust bag the collar 42, and the dust bag attached to it mayhe slid off the suction tube without scattering the dust contained inthe bag.

In operation, the rotation of the motor ting the air after beingcleansed to pass out through its interstices.

Having thus described my invention, ll claim:

1. A. vacuum cleaner consisting of a shaft with a handle, a motorcasing, and motor attached to the end of the shaft, a fan driven by themotor, a vacuum tube in alinement with .the shaft below the motor andthe fan,

a flanged disk surrounding the tan, and a permeable ttcfied" atone endto the flanged" disk and at the other end tjo the vacuum tube both ofwhich are surrounded by" said-dust bag;

2. In 3) Vacuum cleaner the comhinatio n' of a fan, a flanged disksurrounding the top v. and sides of the fan, ,a suction tube in"alimegnentwith the axis of the fan, a. collar ,slidfl anged disksnrrohndin'g the farislnd at its lower end to the collar.

In testimony whereof, I have hereunto signed my name, at Philadelphia,Pennsyl- Vania, this twenty-fourth day of November,
